It was important to minimize the amount of data transferred across the network to effectively recreate a full backup
and equally important to minimize the amount of data required to represent a comprehensive history of backup data.
Doing incremental backup does not take the time or storage that a full backup
Optimized Synthetics eliminates weekly full backups
and reduces server workload and network traffic by offloading synthetic full backup
processing to HYDRAstor.
Using the Exchange Backup API (ESE--Extensible Storage Engine), these 3rd-party products perform a full backup
of Exchange including all databases and log files.
This was a 400,000 square foot assignment with a 400 person trading operation, prime computer center, full food service facility, executive dining, executive offices and a full backup
generator plant with a UPS system.
It keeps one full backup
set to pass on to future generations and calls on another set to keep the cell running.
For example, if a hard drive must be restored, every tape since the last full backup
must be restored to reproduce every file.
Optimized Synthetics offers a simple way to eliminate a full backup
every week and achieve dramatic backup window reduction by allowing storage administrators to back up only changed files for prolonged periods of time.
Exchange administrators can either run a full backup
or back up an individual mailbox or individual mailboxes ("brick-level" backup).
The software automatically spans disks when performing backups, and backs up only new and changed files after the first full backup
There was one customer with 60 hours for a full backup
once a week and 6 hours of incrementals every day, and that came down to 20 minutes every day for full backups
In addition, by keeping recently backed-up data on the system, individual files can be quickly recovered rather than remounting a full backup
Instead of physically copying changes during synthetic full creation--as other vendor products do--new and changed files are marked with pointers, which can then be used to quickly create full backup
NetWorker not only best met the above criteria, it also gave us the option of doing weekly full backups
and daily differentials where a single full backup
was completed only at installation and then updated with numerous incrementals.
Each full backup
used 35 tapes, which were transported weekly to a secure facility.
